Black Sabbath will reportedly be one of the headliners of this summer's Lollapalooza, with advance word of the three-day festival's lineup leaking from a Brazilian website.

According to Tenhomaisdiscosqueamigos.com, Sabbath will appear along with Red Hot Chili Peppers, former White Stripes frontman Jack White and the Black Keys. The group, who will perform as part of the Download festival in the U.K. on June 10, had promised to also perform one U.S. show after cancelling nearly all their massive 2012 reunion world tour plans following guitarist Tony Iommi's lymphoma diagnosis.

The rest of the bill is typically light on classic rock, with more alternative-leaning acts such as Florence + the Machine, At the Drive-In and the Shins landing high spots on the bill. Still, we're going to be there with bells on and we highly suggest our fellow attendees check out Austin, Texas psychedelic rockers the Black Angels.

The line-up is due to be officially announced this Wednesday, April 11 on the festival's official website, so maybe don't book your tickets just yet. Lollapalooza takes place in Chicago's Grant Park between August 3 and 5 this year.
